Adobe posts 64-bit Flash preview for Mac, PC
Adobe today posted "Square," a preview version of 64-bit Flash available for Mac and Windows. Expanding on the original Linux port, it gives users of Mac OS X Snow Leopard's 64-bit mode and 64-bit x86 editions of Windows a truly native plugin instead of having to use a compatibility layer or nothing at all. The release also gives these users performance optimizations specific to 64-bit processors.
Windows users get a specific benefit if they use Internet Explorer 9, as "Square" will use the Direct2D hardware acceleration to render its content using a PC's graphics chipset faster than it would with the main processor. Linux users should get better reliability.
Apart from the need for a 64-bit OS and processor, the hardware requirements are the same as for the 32-bit edition of Flash 10.1. Adobe has stressed that "Square" isn't a pre-release of a future version of Flash in itself but will have its technology rolled into later iterations.
